Reply to comment by landodk in How Much Land Would It Require To Get Most Of Our Electricity From Wind & Solar? by BlitzOrion

You’d need more than that, Western Australia 45% of all domestic rooftops have solar, we cover most of Our needs from solar, but it’s the storage that’s the issue for night time. It can be done, but battery tech needs to get cheaper and it is. In Australia you can buy a 6.6kW system with a battery for 12k USD and it would cover most house holds needs.

The iron flow batteries are on the way. Much longer duration, higher cycles and way lower cost. Consumes some of the energy though.

I'll trust it when I see it at the store. So much tech has been on its way for a decade, "just around the corner" it's ridiculous to even mention them by now.
